3 daysbpf: Clarify handling of mark and tstamp by redirect_peerPaul Chaignon
When switching network namespaces with the bpf_redirect_peer helper, the skb->mark and skb->tstamp fields are not zeroed out like they can be on a typical netns switch. This patch clarifies that in the helper description.

The phy-upstream enum is already defined in the ethtool.h UAPI header and used by the ethtool userspace tool. However, the ethtool spec does not reference it, causing YNL to auto-generate a duplicate and redundant enum. Fix this by updating the spec to reference the existing UAPI enum in ethtool.h.

2025-04-15io_uring/zcrx: return ifq id to the userPavel Begunkov
IORING_OP_RECV_ZC requests take a zcrx object id via sqe::zcrx_ifq_idx, which binds it to the corresponding if / queue. However, we don't return that id back to the user. It's fine as currently there can be only one zcrx and the user assumes that its id should be 0, but as we'll need multiple zcrx objects in the future let's explicitly pass it back on registration.

2025-04-11accel/ivpu: Fix the NPU's DPU frequency calculationAndrzej Kacprowski
Fix the frequency returned to the user space by the DRM_IVPU_PARAM_CORE_CLOCK_RATE GET_PARAM IOCTL. The kernel driver returned CPU frequency for MTL and bare PLL frequency for LNL - this was inconsistent and incorrect for both platforms. With this fix the driver returns maximum frequency of the NPU data processing unit (DPU) for all HW generations. This is what user space always expected. Also do not set CPU frequency in boot params - the firmware does not use frequency passed from the driver, it was only used by the early pre-production firmware. With that we can remove CPU frequency calculation code. Show NPU frequency in FREQ_CHANGE interrupt when frequency tracking is enabled.

This is linked to the VIOMMU object and is intended to be used by a VMM to forward HW events to the virtual machine as part of emulating a vIOMMU. ARM SMMUv3 is the first driver to use this mechanism. Like the existing fault events the data is delivered through a simple FD returning event records on read(). - PASID support in VFIO. The "Process Address Space ID" is a PCI feature that allows the device to tag all PCI DMA operations with an ID. The IOMMU will then use the ID to select a unique translation for those DMAs. This is part of Intel's vIOMMU support as VT-D HW requires the hypervisor to manage each PASID entry. The support is generic so any VFIO user could attach any translation to a PASID, and the support should work on ARM SMMUv3 as well. AMD requires additional driver work.

2025-03-31fuse: add kernel-enforced timeout option for requestsJoanne Koong
There are situations where fuse servers can become unresponsive or stuck, for example if the server is deadlocked. Currently, there's no good way to detect if a server is stuck and needs to be killed manually. This commit adds an option for enforcing a timeout (in seconds) for requests where if the timeout elapses without the server responding to the request, the connection will be automatically aborted. Please note that these timeouts are not 100% precise. For example, the request may take roughly an extra FUSE_TIMEOUT_TIMER_FREQ seconds beyond the requested timeout due to internal implementation, in order to mitigate overhead.

This yields near-optimal code for small constant copies with a ~40kb kernel size increase - Add support for a configurable STRICT_MM_TYPECHECKS which allows to generate better code, but also allows to have type checking for debug builds - Optimize get_lowcore() for common callers with alternatives that nearly revert to the pre-relocated lowcore code, while also slightly reducing syscall entry and exit time - Convert MACHINE_HAS_* checks for single facility tests into cpu_has_* style macros that call test_facility(), and for features with additional conditions, add a new ALT_TYPE_FEATURE alternative to provide a static branch via alternative patching. Also, move machine feature detection to the decompressor for early patching and add debugging functionality to easily show which alternatives are patched - Add exception table support to early boot / startup code to get rid of the open coded exception handling - Use asm_inline for all inline assemblies with EX_TABLE or ALTERNATIVE to ensure correct inlining and unrolling decisions - Remove 2k page table leftovers now that s390 has been switched to always allocate 4k page tables - Split kfence pool into 4k mappings in arch_kfence_init_pool() and remove the architecture-specific kfence_split_mapping() - Use READ_ONCE_NOCHECK() in regs_get_kernel_stack_nth() to silence spurious KASAN warnings from opportunistic ftrace argument tracing - Force __atomic_add_const() variants on s390 to always return void, ensuring compile errors for improper usage - Remove s390's ioremap_wt() and pgprot_writethrough() due to mismatched semantics and lack of known users, relying on asm-generic fallbacks - Signal eventfd in vfio-ap to notify userspace when the guest AP configuration changes, including during mdev removal - Convert mdev_types from an array to a pointer in vfio-ccw and vfio-ap drivers to avoid fake flex array confusion - Cleanup trap code - Remove references to the outdated linux390@de.ibm.com address - Other various small fixes and improvements all over the code * tag 's390-6.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (78 commits) s390: Use inline qualifier for all EX_TABLE and ALTERNATIVE inline assemblies s390/kfence: Split kfence pool into 4k mappings in arch_kfence_init_pool() s390/ptrace: Avoid KASAN false positives in regs_get_kernel_stack_nth() s390/boot: Ignore vmlinux.map s390/sysctl: Remove "vm/allocate_pgste" sysctl s390: Remove 2k vs 4k page table leftovers s390/tlb: Use mm_has_pgste() instead of mm_alloc_pgste() s390/lowcore: Use lghi instead llilh to clear register s390/syscall: Merge __do_syscall() and do_syscall() s390/spinlock: Implement SPINLOCK_LOCKVAL with inline assembly s390/smp: Implement raw_smp_processor_id() with inline assembly s390/current: Implement current with inline assembly s390/lowcore: Use inline qualifier for get_lowcore() inline assembly s390: Move s390 sysctls into their own file under arch/s390 s390/syscall: Simplify syscall_get_arguments() s390/vfio-ap: Notify userspace that guest's AP config changed when mdev removed s390: Remove ioremap_wt() and pgprot_writethrough() s390/mm: Add configurable STRICT_MM_TYPECHECKS s390/mm: Convert pgste_val() into function s390/mm: Convert pgprot_val() into function ...

git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma Pull fwctl subsystem from Jason Gunthorpe: "fwctl is a new subsystem intended to bring some common rules and order to the growing pattern of exposing a secure FW interface directly to userspace. Unlike existing places like RDMA/DRM/VFIO/uacce that are exposing a device for datapath operations fwctl is focused on debugging, configuration and provisioning of the device. It will not have the necessary features like interrupt delivery to support a datapath. This concept is similar to the long standing practice in the "HW" RAID space of having a device specific misc device to manage the RAID controller FW. fwctl generalizes this notion of a companion debug and management interface that goes along with a dataplane implemented in an appropriate subsystem. There have been three LWN articles written discussing various aspects of this: https://lwn.net/Articles/955001/ https://lwn.net/Articles/969383/ https://lwn.net/Articles/990802/ This includes three drivers to launch the subsystem: - CXL provides a vendor scheme for executing commands and a way to learn the 'command effects' (ie the security properties) of such commands. The fwctl driver allows access to these mechanism within the fwctl security model - mlx5 is family of networking products, the driver supports all current Mellanox HW still receiving FW feature updates. This includes RDMA multiprotocol NICs like ConnectX and the Bluefield family of Smart NICs. - AMD/Pensando Distributed Services card is a multi protocol Smart NIC with a multi PCI function design. fwctl works on the management PCI function following a 'command effects' model similar to CXL" * tag 'for-linus-fwctl' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (30 commits) pds_fwctl: add Documentation entries pds_fwctl: add rpc and query support pds_fwctl: initial driver framework pds_core: add new fwctl auxiliary_device pds_core: specify auxiliary_device to be created pds_core: make pdsc_auxbus_dev_del() void cxl: Fixup kdoc issues for include/cxl/features.h fwctl/cxl: Add documentation to FWCTL CXL cxl/test: Add Set Feature support to cxl_test cxl/test: Add Get Feature support to cxl_test cxl: Add support to handle user feature commands for set feature cxl: Add support to handle user feature commands for get feature cxl: Add support for fwctl RPC command to enable CXL feature commands cxl: Move cxl feature command structs to user header cxl: Add FWCTL support to CXL mlx5: Create an auxiliary device for fwctl_mlx5 fwctl/mlx5: Support for communicating with mlx5 fw fwctl: Add documentation fwctl: FWCTL_RPC to execute a Remote Procedure Call to device firmware taint: Add TAINT_FWCTL ...

2025-03-28ublk: add segment parameterMing Lei
IO split is usually bad in io_uring world, since -EAGAIN is caused and IO handling may have to fallback to io-wq, this way does hurt performance. ublk starts to support zero copy recently, for avoiding unnecessary IO split, ublk driver's segment limit should be aligned with backend device's segment limit. Another reason is that io_buffer_register_bvec() needs to allocate bvecs, which number is aligned with ublk request segment number, so that big memory allocation can be avoided by setting reasonable max_segments limit. So add segment parameter for providing ublk server chance to align segment limit with backend, and keep it reasonable from implementation viewpoint.

Pull io_uring epoll support from Jens Axboe: "This adds support for reading epoll events via io_uring. While this may seem counter-intuitive (and/or productive), the reasoning here is that quite a few existing epoll event loops can easily do a partial conversion to a completion based model, but are still stuck with one (or few) event types that remain readiness based. For that case, they then need to add the io_uring fd to the epoll context, and continue to rely on epoll_wait(2) for waiting on events. This misses out on the finer grained waiting that io_uring can do, to reduce context switches and wait for multiple events in one batch reliably. With adding support for reaping epoll events via io_uring, the whole legacy readiness based event types can still be reaped via epoll, with the overall waiting in the loop be driven by io_uring" * tag 'for-6.15/io_uring-epoll-wait-20250325' of git://git.kernel.dk/linux: io_uring/epoll: add support for IORING_OP_EPOLL_WAIT io_uring/epoll: remove CONFIG_EPOLL guards

Pull io_uring zero-copy receive support from Jens Axboe: "This adds support for zero-copy receive with io_uring, enabling fast bulk receive of data directly into application memory, rather than needing to copy the data out of kernel memory. While this version only supports host memory as that was the initial target, other memory types are planned as well, with notably GPU memory coming next. This work depends on some networking components which were queued up on the networking side, but have now landed in your tree. This is the work of Pavel Begunkov and David Wei. From the v14 posting: 'We configure a page pool that a driver uses to fill a hw rx queue to hand out user pages instead of kernel pages. Any data that ends up hitting this hw rx queue will thus be dma'd into userspace memory directly, without needing to be bounced through kernel memory. 'Reading' data out of a socket instead becomes a _notification_ mechanism, where the kernel tells userspace where the data is. The overall approach is similar to the devmem TCP proposal This relies on hw header/data split, flow steering and RSS to ensure packet headers remain in kernel memory and only desired flows hit a hw rx queue configured for zero copy. Configuring this is outside of the scope of this patchset. We share netdev core infra with devmem TCP. The main difference is that io_uring is used for the uAPI and the lifetime of all objects are bound to an io_uring instance. Data is 'read' using a new io_uring request type. When done, data is returned via a new shared refill queue. A zero copy page pool refills a hw rx queue from this refill queue directly. Of course, the lifetime of these data buffers are managed by io_uring rather than the networking stack, with different refcounting rules. This patchset is the first step adding basic zero copy support. We will extend this iteratively with new features e.g. dynamically allocated zero copy areas, THP support, dmabuf support, improved copy fallback, general optimisations and more' In a local setup, I was able to saturate a 200G link with a single CPU core, and at netdev conf 0x19 earlier this month, Jamal reported 188Gbit of bandwidth using a single core (no HT, including soft-irq). Safe to say the efficiency is there, as bigger links would be needed to find the per-core limit, and it's considerably more efficient and faster than the existing devmem solution" * tag 'for-6.15/io_uring-rx-zc-20250325' of git://git.kernel.dk/linux: io_uring/zcrx: add selftest case for recvzc with read limit io_uring/zcrx: add a read limit to recvzc requests io_uring: add missing IORING_MAP_OFF_ZCRX_REGION in io_uring_mmap io_uring: Rename KConfig to Kconfig io_uring/zcrx: fix leaks on failed registration io_uring/zcrx: recheck ifq on shutdown io_uring/zcrx: add selftest net: add documentation for io_uring zcrx io_uring/zcrx: add copy fallback io_uring/zcrx: throttle receive requests io_uring/zcrx: set pp memory provider for an rx queue io_uring/zcrx: add io_recvzc request io_uring/zcrx: dma-map area for the device io_uring/zcrx: implement zerocopy receive pp memory provider io_uring/zcrx: grab a net device io_uring/zcrx: add io_zcrx_area io_uring/zcrx: add interface queue and refill queue

Add LANDLOCK_RESTRICT_SELF_LOG_SUBDOMAINS_OFF for the case of sandboxer tools, init systems, or runtime containers launching programs sandboxing themselves in an inconsistent way. Setting this flag should only depends on runtime configuration (i.e. not hardcoded). We don't create a new ruleset's option because this should not be part of the security policy: only the task that enforces the policy (not the one that create it) knows if itself or its children may request denied actions. This is the first and only flag that can be set without actually restricting the caller (i.e. without providing a ruleset). Extend struct landlock_cred_security with a u8 log_subdomains_off. struct landlock_file_security is still 16 bytes.
